"At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate, and replace the savage races throughout the world"

This quote by Charles Darwin suggests that in the future, the more advanced and civilized races of humans will ultimately replace the less advanced and "savage" races. This replacement is most likely to happen within a couple of centuries, which is a relatively short quantity of time. This recommends that the more advanced races will have a substantial advantage over the less advanced races, and will have the ability to outcompete them for resources and territory. This might be due to the more advanced races having access to much better technology, education, and resources. This could lead to the less advanced races being pressed out of their standard lands and way of lives, and ultimately becoming extinct. This quote by Charles Darwin is a tip of the power of progress and the value of comprehending the consequences of our actions.
